The heir to the imperial throne is the strongest sentinel in history. He had a beloved guide and fiancée, but she died in battle.
The crown prince was devastated by the loss of his guide. His mind was severely damaged, and he had to rely on exceptionally powerful mental strength.
So the empire's general found a mysterious young man with black hair and brown eyes: Zhou Yi, the person in the entire universe most compatible with the crown prince, to serve as his new guide.
Zhou Yi: A guide? Sure. Pay me.
General: You're going to guide the empire's crown prince!
Zhou Yi: Oh, sure. That'll cost extra.
The crown prince kept Zhou Yi at arm's length because he still held his fiancée in his heart.
Yet he had no choice but to depend on his new guide.
Zhou Yi: No problem. I'm getting paid.
Later, after they had faced life and death together, the crown prince realized he had fallen in love with Zhou Yi again.
...But he discovered that Zhou Yi seemed to love nothing but money.

Zhou Yi was an assassin. His codename in the organization was 25, so he'd always used that number as his name.
He had the highest mission completion rate on the rankings. He rarely thought about anything beyond earning money to support his family.
That is, until the upright crown prince investigated his underground organization and uncovered everything. Zhou Yi's personal information was leaked, too.
After assassinating many powerful figures, the assassin known as 25 was wanted across the stars.
Zhou Yi thought that ever since he transmigrated to this world after finishing the college entrance exams, nothing had gone right for him.
He'd been kidnapped from the start. He'd endured all kinds of abnormal jobs, including being dropped into a hunting ground as prey, thrown into an arena to fight to the death for other people's entertainment, and finally becoming an assassin... If he hadn't escaped back then, he'd have been dead by now.
All he wanted was to work in peace. Still, although the crown prince had cost him a relatively well-paid assassin job, what the man was doing was right, and it fit the core values he'd learned back home.
After being placed on the wanted list, Zhou Yi went back to scavenging in the radiation zone. Then, one day, he found the gravely wounded crown prince, barely clinging to life in a high-radiation area.
Zhou Yi agreed with the crown prince's ideals. He decided to heal him and send him back to that corrupt place, so he could keep bringing those unscrupulous powerhouses to heel.
To avoid being recognized, Zhou Yi changed his build and appearance, and even disguised himself as a woman.
But then the unexpected happened.
The crown prince scavenged alongside him every day, and one day suddenly proposed to him.
Zhou Yi was stunned. He had no idea how to explain that he was a man, and the wanted poster with his face on it was probably still in the crown prince's office.
...He decided to fake his death.
